ABSTRACT This study presents a comparative analysis of the energy‐saving potential newly developed Pakistani regulation, Energy Conservation Building Code–2023, and International Code–2021 for residential buildings in Pakistan. Utilizing an EnergyPlus‐based simulation tool, energy consumption typical house was modeled three different climate zones Pakistan: 0B (hot dry), 3B (warm 7B (very cold). The focused on evaluating how improvements building envelope, as mandated by each code, impacted overall building. Results revealed that Code–2023 performs better than hot climates such Karachi. Specifically, achieved 24% reduction annual consumption, compared to 21.8% Code–2021. However, demonstrates higher savings warm cold (Quetta Skardu). In these very 7B), led reductions 47.32% 79.5%, respectively, 45.3% 33.86% Code–2023. variation is attributed stringent U‐value standards set Code–2021, particularly colder climates. evaluates strengths limitations both codes concerning Pakistan's diverse climatic conditions, underscoring need region‐specific conservation optimize efficiency. It highlights necessity ongoing Research Development enhance effectiveness nationwide applicability
